SAFETY PRECAUTIONS

Please follow the safety precautions, as failure to do so can lead to malfunction of the system-, and risk of injury.

1. If the SYMBIONIC LEG® 3 loses power, the knee loses its ability to provide stance support. In such cases it is recommended to manually engage the integrated extension lock to lock the knee in full extension. The knee allows full weight bearing when locked.

2. Make sure that the user is able to recognize the auditory and/or vibratory signal for power loss when completing daily living activities.

3. The knee-module stance-control settings may be customized to maximize security or terrain recognition, depending on the user's preference. For maximum safety, it is recommended that a handrail be used when descending stairs and ramps. Steep inclines or declines (above 20°) may trigger the stair response, resulting in unexpected foot alignment.

4. Improper adjustment of the SYMBIONIC LEG 3 will cause suboptimal function, which can increase the risk of falls. The SYMBIONIC LEG 3 must only be fitted by a clinician who has attended and passed an Össur certified SYMBIONIC LEG 3 education program.

5. When making adjustments to the SYMBIONIC LEG 3, ensure the user is seated or in a stable standing position.

6. The healthcare practitioner must provide each patient with training for appropriate use and proper application of the system.

7. The user should stop walking immediately if alarm signals are felt or heard. Proceed to walk with caution.

8. The SYMBIONIC LEG 3 is designed for everyday use. The prosthesis must not be used for sports or constant high-impact activities (e. g. running, climbing, etc.).

9. The SYMBIONIC LEG 3 is battery operated and caution should be taken about exposure to water, excessive mechanical shocks or vibrations.

10. Avoid impact to the interface panels on the back of the knee module and to the interface panel at the front of the ankle module. Damage to these panels or any of their components may cause product malfunction. Do not use if the product enclosure or covers are broken.

11. Do not attempt any repairs or service functions to the SYMBIONIC LEG 3. This may cause damage to the prosthesis, possible malfunction, or failure, and voids the warranty. The battery can only be changed by an authorized service technician.

12. The power supply provided with the unit is certified to comply with medical electrical equipment standards and it is therefore not safe to use any other power supply equipment.

13. Do not use in highly electrical and/or magnetic environments (e. g. electrical transformers, high-power radio/TV transmitters). Avoid exposure to extreme heat and/or cold (see chapter Technical Specifications). Avoid exposure to intense dust, smoke, or mechanical vibrations.

14. Not suitable for use in the presence of a flammable, anesthetic mixture containing air oxygen or nitrous oxide.

15. Follow local ordinances or regulations for proper disposal of device, accessories, and packaging.

16. Batteries should be disposed of in accordance with local laws and regulations. They should not be incinerated.

76

17. Caution should be taken with respect to the use of the SYMBIONIC LEG 3 inside of a motor vehicle. Inadvertent movement of the ankle may interfere with control functions of brake and/or accelerator. When preparing to drive, turn the SYMBIONIC LEG 3 off (see chapter Power OFF).

Caution: U.S. Federal law requires this device to be sold by a prosthetist and on the order of a physician.

SAFETY STANDARDS AND CLASSIFICATION

The SYMBIONIC LEG 3 is tested and certified to comply with the IEC/EN60601-1 standard for electrical safety of medical devices, the IEC/EN60601-1-2 standard for electromagnetic compatibility for medical electrical devices, and ISO 10328.

Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.”

SYMBIONIC LEG 3 FUNCTIONS1. ANKLE FUNCTIONSDorsif lexion during swing phaseThe user is actively assisted in swing phase, as the ankle uses motor power to dorsiflex the foot:

• Improves gait symmetry.• Reduces the likelihood of catching the toe (improves ground

clearance).

Adaption of ankle positionAs the user walks, the ankle adapts to inclines, declines, and stairs.

• Offers a natural gait dynamic.• Reduces pathological gait.• Reduces the risk of falls.

Note: Steep inclines or declines (above 20°) may trigger stair response, resulting in unexpected ankle adaptation.

Heel height adaptationThe ankle of the SYMBIONIC LEG 3 provides the user with the ability to automatically adjust the ankle position to a range of shoe heel heights, conveniently allowing a choice of shoes.

Sitting downWith the relax mode activated the ankle of the SYMBIONIC LEG 3 will plantar flex in sitting (it is off by default).

• More natural appearance.• Enhanced comfort.

Standing upThe ankle of the SYMBIONIC LEG 3 assists in standing up from a seated position through an adaptation of its ankle position.

• More controlled transition from sitting to standing.

8

Kneeling downThe SYMBIONIC LEG 3 has the ability to plantar flex when kneeling and also when lying down.

• More natural appearance.• Enhanced comfort.

2. KNEE FUNCTIONSAutomatic adjustment to dif ferent surfaces and walking speed

• Microprocessor controlled stance phase resistance assists the user in maintaining knee stability on a variety of surfaces.

• Microprocessor controlled swing phase resistance samples and adjusts to the users walking speed during swing at a rate of 1000 times per second (1000 Hz). This allows the user to achieve comfortable and symmetric transitions among wide ranges of walking speeds.

Excellent adjustability• Adjustable stance flexion provides adjustable stance resistance for

varying degrees of knee flexion during loading response.• Adjustable stance extension provides adjustable stance resistance to

knee extension between loading response and midstance. Leads to dampened extension force and shock absorption.

Magnetorheologic f luid actuator means light weight feel and frictional resistance

• Magnetized fluid provides frictional resistance to flexion and extension movement.

• The actuator weight is located proximal in the knee providing a light-weight feel during swing phase.

System f lexibility and simplicity• Integrated sensor pylon allows for simple connections to foot and shock

systems without use of specialized pylons.• Provides the ability to change height or foot rotation without

recalibration or system reset.• Contributes to low build of prosthesis and allows for increased

number of foot options.

2. CALIBRATION OF KNEE MODULE Requirements for calibrationRHEOLOGIC™ software is required to calibrate the knee module.Refer to the RHEOLOGIC technical manual for information on how to connect to the knee module and modify adjustable parameters.

The following values are acceptable calibration ranges for angle and load:• Angle (-2 to 3°)• Toe load (-2.5 to 2.5)• Heel load (-2.5 to 2.5)

If the calibration values are out the given ranges, calibration is required

How to calibrate the knee module1. Before starting make sure there is no load on the knee and do not

connect the socket to the knee.2. Make sure the knee is fully extended.3. Connect to the knee using the RHEOLOGIC software.4. Open the “Calibrate” tab in the RHEOLOGIC software and press the

“Calibrate” button.5. When calibration is complete the knee module will provide a

sound/vibration signal.

Important: Improper calibration (for example if load is applied on the knee or socket is connected) affects the knee's ability to perform optimally and may compromise the user's safety.

3. BENCH ALIGNMENTOptimize length/alignment of pylon and adaptors

• Fit the foot with the selected cover and shoe.• Establish the correct height of the prosthesis using the appropriate

components.• Ensure that the alignment is correct in the sagittal and coronal

planes. Correct position of the alignment reference line should bisect the socket, fall between 5 mm anterior to 5 mm posterior of the knee center of the knee module and fall on the posterior 1/3 of the carbon plate (Figure 1).

Caution: As the alignment reference line is positioned more posterior to the knee center, the user will experience more stance flexion during loading response. Additional voluntary control will be required to maintain knee stability when power is off.

Important: At maximum flexion, maintain minimum distance of 3 mm (1/8") between the knee module and the socket. At maximum flexion where contact cannot be avoided due to socket volume, ensure contact is on the frame, directly below the user interface panel. For maximum pressure distribution, maintain a flat and cushioned contact surface (Figure 3).

Make sure the connection cable lies flat against the surface of the prosthesis because a loose cable can get caught. Observe the cable position during walking, and make changes to the

assembly if necessary.

Use of heel wedgesOptimum functional benefits will be achieved only when the rollover

12

function is optimized. The heel wedge can influence the heel-to-toe function. Start changing the heel resistance to improve foot response by adding a heel wedge. The 2°, 4°, and 6° wedges can be substituted to customize the stiffness of the heel and achieve the desired functional characteristics. A combination of wedges may be used. Have the user walk on even ground and assess proper heel-to-toe function.

Temporary Wedge Placement (Figure 4)• Cut the wedge to the width of the foot module.• Roughen the upper and lower surface of the wedge with abrasive paper.• Place the wedge in the angle of the heel and foot module.• Secure the wedge in position with tape wrapped around the foot

module.Permanently fix wedges when ankle module is used for more than a couple of days. Temporarily fitted wedges will move out of position and cause functional issues. Failure to do so can void the warranty.

4. HEEL HEIGHT ADJUSTMENT – ANKLE MODULEThe ankle module can be adjusted for variable heel height. The heel height adjustment ensures correct alignment of the prosthesis.

Heel height adjustment on the bench• Wear suitable footwear and ensure free ankle motion.• With power on and the prosthesis standing on a level surface, initiate

heel height adjustment by holding down the upper button and pressing the lower button twice (Figure 9).

Note: Pay attention to the audible feedback.

Note: If the heel height exceeds 50 mm (2"), a signal will be heard and the unit will not adjust to the heel height. Change shoes for lower heel height and repeat the adjustment. Ensure free ankle motion.

5. ANKLE CALIBRATION Calibration must be performed during the initial fitting to calibrate the ankle module to the user's individual gait. During calibration, the ankle module recognizes the user's specific gait parameters, allowing for accurate and consistent terrain detection. For calibration, the user must walk on level ground for at least 15 consecutive strides without interruption.

• Have the user stand still.• Make sure the keypad is active (the. LED will blink green and yellow).• Make sure the user has access to a path on level ground long enough

to complete at least 15 strides without interruption.• Enable calibration (Figure 9).• Have the user walk on level ground at a self-selected walking speed

until completion of calibration is confirmed by a beep and vibration (the. LED will blink green). The system is now properly calibrated to the user and enabled for normal adaptive functions.

Note: Make sure the surface is completely flat. It is recommended that calibration be performed on an indoor surface. No sharp turns should be taken during calibration.

Note: The user may take gentle turns during the calibration walk. If the calibration is not completed after approximately 15 strides, see below.

1312

Ankle calibration troubleshooting:• Ensure the correct alignment.• Ensure there are no extreme gait deviations, such as significant

circumduction or rotation, as this may prevent the completion of calibration.

• Ensure a consistent walking speed.• Avoid walking in a circle or sharp curves.• If calibration is not confirmed after 15 strides, you must perform the

calibration again.• If the alignment is changed, you must perform the calibration again.• If for any reason the LED turns red, the procedure must be repeated.

6. OPTIMIZE SETTINGS OF ANKLE MODULE STAIRS (Figure 10)• During stair ascent, the ankle module will raise the toe. This will

facilitate stair ambulation and improve gait symmetry.• When leading with the prosthetic side, the ankle module will adapt to

this position after the second prosthetic step on the stairs.

Note: Pay attention to transitions to and from stairs.

When the ankle module is activated for the first time, the default manufacturer settings will be enabled. In the default manufacturer settings, the stair response is turned off. To change the stair response, see Figure 10.

Relax mode / chair exit mode (Figure 11) Relax mode allows the ankle to move into full plantar flexion, which will provide improved body symmetry to the natural limb when sitting. Relax mode is off by default. Initiate Relax mode in a sitting position by extending the knee for at least 2 seconds. This provides a more natural ankle position when sitting with the lower leg extended.

Following the Relax mode, the ankle module will move into Chair Exit mode. To initiate this, use one of the following methods:

1. Tap the heel of the foot. 2. Flex the knee and place the foot beneath the chair. Lift the foot to

allow the adjustment to take place.

The ankle will move to dorsiflexion, which enables the user to bring the leg further back, providing a more controlled transition from sitting to standing. The ankle will move back to neutral after the first step.

7. FINISHINGPermanent Wedge Placement

• Apply adhesive to the upper side of the wedge only.• Locate it in the foot/heel junction, and position it before the adhesive

sets.• For split toe feet, first install the heel wedge and then remove a thin

slice in the middle by cutting with a sharp knife through the split in the carbon foot module (Figure 5).

Flex-foot sock FCX63007 (Figure 6)To protect the cover a Flex-Foot sock is fitted over the foot module before applying the cover. The sock should fit loosely in the heel area. To hold

14

the Flex-Foot sock in place, attach the self-adhesive velcro tabs to the sides and front of the ankle. Press the Flex-Foot sock firmly onto the tabs to hold in place.It is important that the Flex-Foot sock doesn't slip down, as this will cause interference with the ankle module function and performance.

Foot cover removalIf you need to remove the foot cover, hold down the cosmetic cover with a hand on the rear aspect of the cosmetic cover. The heel module will snap out of the heel clip. Continue to pull and remove the foot completely.

Note: Do not use a Flex-Foot shoehorn or any other lever to remove the foot cover, as this may cause damage to the ankle module.

Socket/frame contact points• Do not remove the unit's protective cover! This will immediately void

the SYMBIONIC LEG 3 warranty.• Care should be taken when configuring the socket/frame and

adapters so that contact only occurs at the posterior apex of the SYMBIONIC LEG 3.

• The SYMBIONIC LEG 3 may be fit with continuous or discontinuous foam covers.

• Össur recommends fitting the SYMBIONIC LEG 3 with a discontinuous cover.

• Do not use talcum powder to eliminate noise caused by the application of a cosmetic cover. It may lead to malfunctions and early deterioration of mechanical parts. Instead use silicone spray. Be careful to apply it only to the knee cover.

• Once the foam cover has been applied, swing phase settings may need modification.

Follow-up procedure checklistDuring follow-up visits, the following procedures are recommended to ensure that the SYMBIONIC LEG 3 is operating at an optimal level for the user:1. Evaluate swing phase elements: heel rise, terminal impact, and

extension rate. Adjust flexion target angle and/or swing extension resistance as needed.

2. Evaluate stance phase elements: stance flexion / stance extension. Adjust as needed for proper support on level ground, ramps, and stairs.

3. Ask the user if any warning signals have been encountered during the period of use.

4. Check knee module calibration. Make sure calibration is within specified limits.

5. If any new adjustments are made to the knee module, make sure the new settings are stored on the mobile device as a new setting for the user.

USER TRAINING

Start the training after the ankle module is aligned and calibrated. Ensure full function with all connections secured.

1514

Heel height adjustment when wearing the prosthesisIf shoes are changed, then the heel height may be adjusted while the user is wearing the prosthesis.

ADVISE THE USER TO FOLLOW THESE INSTRUCTIONS1. Take a seat and ensure the prosthesis is positioned flat (heel and

forefoot area) on the ground.2. Ensure the power is on.3. To initiate heel height adjustment, hold down the upper button and

press the lower button twice (Figure 9). (The system will confirm with a beep and vibration.)

4. Heel height adjustment will start. (The system beeps and vibrates a second time.)

5. Immediately lift the prosthesis from the ground to allow for ankle adaptation!

6. The actuator will move the prosthesis into a vertical position. (The system will confirm with a beep and vibration, then LED will blink green and yellow.)

7. Heel height adjustment is complete.

Note: Do not fit boots or shoes that cover the ankle area! The ankle must be able to move freely over the full range of ankle motion. To ensure proper function, do not restrict the motion of the ankle.

• CHARGING: Train the user on how to charge the unit.

• HEEL HEIGHT ADJUSTMENT: Encourage the user to switch shoes or try out barefoot walking using the heel height adjustment.

• CURBS: Ask the user to take a long step onto and off a curb. This will limit the ankle adaptation and prevent false ankle adaptation. Note: Walking across high curbs may initiate the stair response!

• SITTING: Ask the user to sit down and position the shank at over 20° relative to the ground (stretch legs). To allow for the Relax mode, the prosthesis has to be slightly unloaded. The ankle module will move into a plantar flexed position (toe down).

• CHAIR EXIT MODE: Ask the user, while in a seated position, to move the prosthesis under or close to the chair. ankle module will dorsiflex (toe up) to facilitate standing up. Be aware that the first step after exiting will be atypical; the foot will then adjust to walking.

• LEVEL GROUND: Ask the user to walk at a slow and a fast speed. Observe the dorsiflexion in swing.

• RAMPS: Ask the user to walk up and down on a shallow ramp and a steep ramp. Observe the ankle adaptation, and ask the user whether she/he can sense it.

• STAIRS: Ask the user to walk up and down on stairs. Advise him/her to lead with the prosthetic side while walking upstairs and to lead with the prosthetic side when going down. This will provide stair adaptation after the first step on stairs. Note: Instruct the user to be careful walking downstairs for the first

16

time, since he/she will not be used to the dorsiflexed ankle position. Encourage the user to switch shoes or try out barefoot walking using the heel height adjustment.

• TOE LIFT: Very slow walking speed won't trigger toe lift.

• HALF STEP: Sharp turns, zigzagging, or stepping up high curbs may cause dorsiflexion.

• POWER LOSS: The foot will return to the latest preset heel height position, and the knee module will turn off.

EXTRA FUNCTIONS – See Figure 9

MANUAL ANKLE OPERATION• Use the upper and lower button to move the foot.• If, during use, ankle motion is repeatedly restricted for any reason, the

foot enters an error state and manual ankle operation is enabled automatically. An alarm will sound and the LED will blink red and yellow, with the green LED steadily on. The motor will retry three times before manual ankle operation is enabled.
